The primary function of the brainstem is ensuring basic vital life functions such as heartbeat, blood pressureand breathing. (ii) It carries water and minerals from the roots to the other parts of the plant. Creeping plants have weak stem so these plants can’t stand erect in air and grows horizontally on the soil. most ferns, iris The brainstem is the region of the brain that connects the cerebrum with the spinal cord.It consists of the midbrain, medulla oblongata, and the pons.Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord. Learning Objectives Summarize the main function and basic structure of stems Such stem also act as a means of vegetative propagation. Functions of stem: Primary or main functions: . Storage of nutrients. Some stems perform the function of storage of food, support, protection, and vegetative propagation. The plant stem including its outermost bark has multiple uses ranging from logs, firewood, lumber, source of pulp for paper making, source of food, fiber, medicine, latex, tannin, dye and many more. Textures include woody, herbaceous and suffrutescent. The production of new living tissue. A culm is a stem found in grass plants such as corn and rice.

A second, closely-related function is to transport food materials manufactured in the leaves to all other parts of the plant. The stem is the portion of the plant that sits above the ground. Functions of the stem: In plant growth and development, the plant stem performs the following functions – A stem connects the roots to the leaves, provides support, stores food, and holds the leaves, flowers, and buds. What are the functions of stems? A second, closely-related function is to transport food materials manufactured in the leaves to all other parts of the plant.

The stem bears floral buds (terminal or axillary) that grow into flowers; The young stem is green in colour and thus it is photosynthetic. It forms the foundation of the method of shooting and contains leaves, flowers and fruits.

Various forms of aerial stems exist, including runners, offshoots, crowns, stolons and spurs. Along with water, the stem carries products from photosynthesis and nutrients to the roots and leaves. Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants. But, what about the stem cells that turn into our blood cells?
